Performing Tayammum

Tayammum consists of the following steps:

1. Finding a piece of ground which is free of najaasah. This could be any natural surface such as rock, sand or dust.
2. Recite the bismillah.
3. Make niyyah, or intention to make tayammum.
4. Place the hands on the surface of the ground.
5. Lift hands with palms downwards, ensuring that no dust remains, may rub them together
6. Rub face with hands.
7. Press hands to ground and touch sides of hands together.
8. Rub right arm with left hand, from the fingers to the elbow, and back along the inner arm to the hand. Do the same with the other arm.

The same conditions that invalidate wudu also invalidate tayammum. In addition, a person's tayammum is invalidated as and when water becomes available.
